Abstract
An instrumented ball-bearing includes a rotating part, a non-rotating part, and an assembly for detecting rotation parameters. The assembly for detecting rotation parameters includes an encoder and a sensor. The sensor is integrated with the non-rotating part. The sensor includes a sensor unit and at least a microcoil. The microcoil has a substantially planar winding. The microcoil is positioned in the sensor unit of the non-rotating part such that the microcoil is positioned axially opposite the encoder.
